1. A device, comprising:

  • a headset;

    a first acoustic sensor on the headset having an output signal;

    a second acoustic sensor on the headset having an output signal;

    modulator circuitry configured for;

    receiving (i) a carrier signal and (ii) the output signal of the second acoustic sensor; and

    modulating the received carrier signal with the received output signal of the second acoustic sensor to generate a modulated output signal reflective of the output signal of the second acoustic sensor;

    combining circuitry configured for;

    receiving (i) the output signal of the first acoustic sensor and (ii) the modulated output signal; and

    combining the output signal of the first acoustic sensor and the modulated output signal to generate a composite downlink signal for transmission over a common conductor; and

    first and second electrical connections configured for providing a connection to a terminal device;

    wherein at least one of the first and second electrical connections is coupled with the combining circuitry for directing the composite downlink signal to the terminal device.
